MP 1,1-5,1 Mac Pro 5,1 Gigabyte/Apollo Issue.

Hello All!

I've had the Titan Gigabyte installed and working wonderfully on my Mac Pro 5,1 (High Sierra) for two + years now. I'm still doing a soft boot into Windows.
Everything was working just fine yesterday. Today? NO!

After a soft boot into Windows I can see that the Titan is recognized, as is the Apollo (x8P) however when I reboot my Mac it's not being recognized. The "Host" light on the Apollo is not on nor is my Apollo accessible in my Sound Prefs.

Any suggestions would be VERY welcome. I'm in France at a studio I put together for a friend and I'm leaving on Wednesday so, time is of the essence!

Thanks so much!

Update: I switched Thunderbolt inputs on the Apollo and unplugged some external Hard Drives and now it works????
Any suggestions as to why this would have fixed the issue would be welcomed.

Thanks again!
